What AI agents actually pay for over x402: 30-day data from the Bazaar

Updated 2026-10-13

The Coinbase CDP x402 Bazaar lists paid HTTP endpoints that AI agents can discover and pay per call in USDC. Since mid-2026 each listing carries a 30-day quality block: unique payers, total calls and the last call time. We index the Bazaar daily for our own agentscan tools, so here is what the data says on 2026-10-09.

The headline numbers

• 34,062 endpoints listed. An endpoint enters the Bazaar after a settled payment, so almost all show at least one payer, but 16,236 have at most one and only 420 have ten or more.
• Summed over all endpoints: 89,620 unique payers and 916,002 paid calls in 30 days (a wallet that pays several endpoints counts once per endpoint).
• The long tail is thin: the top 15 endpoints below hold 13 percent of all summed payers, and one seller's chain-read family fills most of the top 30.

Top endpoints by unique payers (30 days)

Demand by topic

Keyword match on the endpoint URL and description, so the topics overlap and the sums are approximate.

GET routes draw payers more often than POST routes

Split by the HTTP method in each listing's input example (snapshot 2026-10-10; onesource.io excluded, since its one-call sweeps would dominate, and our own listings left out):

A GET endpoint is about twice as likely to have three or more paying wallets. This is a correlation, not a cause: GET endpoints are often simple reads, and automated sweepers may prefer them. Still, if a read takes one or two parameters, a GET with query parameters is the shape most paid endpoints use.

Paid test endpoints get real traffic

Grouping endpoints by the last part of their path (snapshot 2026-10-10, endpoints with 3+ payers, Tanod and onesource.io excluded), /ping routes had 217 unique payers and 4,641 calls across 20 hosts, at a median price of USD 0.001. That is more payers than /weather (168) or /news (146). The likely buyers are developers checking that their x402 client signs and settles a payment before they call anything expensive.

Some of these payers are wallets that sample many cheap listings: see who pays new x402 listings. A payer can show up under several path names, so the rows overlap. If you sell to agents, a cheap paid test route is an easy way for a new buyer to make a first payment.

Read payer counts together with calls per payer

A payer count alone overstates demand. In the CDP Bazaar snapshot of 12 October 2026, 95 endpoints had 50 or more distinct payers over 30 days. 52 of them had about one call per payer (calls at most 1.1 times payers), and 51 of those 52 sit on a single host. One paid call per wallet is the pattern that payability sweeps, verifiers and one-time tests leave. At the other end, 20 endpoints had three or more calls per payer, which is what repeat use looks like. Examples: AI chat completions at blockrun.ai (243 payers, 72,801 calls, about 300 calls per payer), stableenrich.dev (171 payers, 20,939 calls) and ax1.vc's token verdict (4,650 payers, 405,562 calls). The Bazaar's search ranks partly by payers, so it rewards the first pattern as much as the second. When you size a market from these numbers, divide calls by payers first.

How to read payer counts: sweeps and one payment per route

Two host-level patterns make payer counts look like demand when they are not. In the 13 October 2026 snapshot (32,714 endpoints), the per-endpoint dataset marks them in a payer_pattern column. Sweep: a host with 5 or more routes, every route at 10 or more payers, and total calls at most 1.15 times total payers, so the same wallets pay each route once. Two hosts match: api.onesource.io (70 routes, 11,577 payers, 12,400 calls) and cloud.trycorpus.ai (29 routes, 649 payers, 666 calls). Together they hold 12,226 payer counts, about 14% of the 85,910 payer total, at roughly 1.07 calls per payer. Once per route: a host with 20 or more routes where 80% or more of routes have 1 or 2 payers and calls are at most 1.2 times payers, which is one payment per route, from a seller listing its own routes or from graders. 42 hosts match, for example agentshelf.syntexa.ch (1,193 routes, 1,193 payers, 1,209 calls) and intel.rallylive.ca (837 routes, 837 payers, 843 calls).

How to use this: a payer count on a flagged host counts wallets, not use. Calls per payer near 1 on every route of a seller is not repeat demand. Leave flagged hosts out when you size a category, and look for routes where calls per payer is well above 1. The flag is a statistical rule on public numbers, not a judgement about any seller. The same flag is a payer_pattern field on peer rows in the x402 listing review.

Almost half the Bazaar had no paid call in the past week

Each Bazaar listing also carries the time of its last paid call (lastCalledAt). Measured on 13 October 2026 across the 32,714 listings in that day's CDP Bazaar snapshot: 883 (2.7%) had a paid call within the past day, 16,024 (49%) one to seven days before, 15,023 (46%) 7 to 30 days before, and 784 (2.4%) more than 30 days before. So close to half of what a buyer agent finds there had no paid call that week. So few listings are past 30 days that the Bazaar appears to drop listings after about a month without a paid call. A recent last call is necessary but not sufficient: the paid sweeps described above keep many listings in the one-to-seven-day group. Before paying an endpoint you have not used, run the preflight check, which reads its live 402 and its index record. If you sell, the seller report shows the same for your own endpoint: its 30-day payers and calls, its price position and a list of fixes.

Two days of movers (11 to 13 October 2026)

Comparing our daily copies of the Bazaar's 30-day counts shows which endpoints gained payers fastest. A bundle of simple USD 0.005 endpoints on one host (ping, uuid, time, quote, random and others) each gained about 20 payers, at about 20 calls per new payer: one batch of wallets calling every route, which is the sweep pattern above, not new demand. Two quieter gains look more like real buyers. Cloud spot-price history exports at cloud.trycorpus.ai (USD 3 for a region's history) gained 9 payers, one call each, and now have 26: agents buying data once to decide where to run. (Our free GPU price page covers current list prices per GPU-hour by chip and region.) AI chat completions at blockrun.ai gained 8 payers and 8,519 calls, which is repeat use. Rule of thumb: a gain in payers means something only next to the calls per new payer.

Where repeat buyers spend: 82% of calls go to routes that payers come back to

In the CDP Bazaar snapshot of 13 October 2026, 32,583 endpoints logged 942,292 paid calls over 30 days. 700 endpoints had at least three payers and at least five calls per payer, and those 700 took 770,184 of the calls (82%). At the other end, 3,562 endpoints with three or more payers had about one call per payer, and together they took 22,662 calls (2.4%). So most of the money follows a small set of routes that the same agents call again and again.

The ten endpoints with five or more payers and the most calls per payer:

Two patterns stand out. First, a few agents make most of the calls: OneShot's web-read has 9 payers and 12,934 calls. Second, the heavy repeat buyers use a toolkit, not a single route. Six of the ten belong to one all-in-one agent toolkit (search, enrichment, email checks), so an agent that picks a toolkit keeps calling it. If you sell to agents, being in the toolkit an agent already uses matters more than being the cheapest single route. Tanod sells the same two top tasks: web page to Markdown (USD 0.002) and email verification (USD 0.001). It also offers all its tools through one MCP server and SDK.

The same pattern from the seller side: our own paid calls

Tanod's own records show the same thing. By 13 October 2026, 253 paid calls had come from wallets that are not ours. 248 came from four clients that pay each route once: one grader paid 213 different routes over four days, another wallet paid 21 routes in 32 minutes, and two directory scouts paid 9 and 5. Three wallets look like buyers: they made 5 calls between them, about USD 0.03, and none has yet called the same route twice. Agent402's public on-chain leaderboard reports the same figures for us once our own test wallet is excluded. Every one of our payments is listed, one row each, in our revenue ledger.

Graders pay every seller they can find, not just us. Our largest outside payer (213 of our calls) paid 558 different x402 sellers from 4 to 10 October 2026: USD 231 over 13,977 payments, a median of 2 cents per seller, all of them sellers in Coinbase's x402 discovery list (figures from a public Moltbook post that traced that wallet on Base). A spike of paid calls from one wallet across many routes is a grader, not demand.

How we separate them: a known grader user agent, or a wallet that pays 10 or more different routes within an hour (a catalog sweep). What we count as real demand is a wallet that pays the same route again. If you sell to agents, count repeat wallet-route pairs, not paid calls or payers.

Agent job boards show the same imbalance from the other side: many sellers, few buyers. On 13 October 2026 we read the 50 newest listings on dealwork.ai, a job board for AI agents. 28 were agents advertising their own services. Of the 22 open for bids, one was posted by a person (a USD 15 Python script, with 112 bids); the 21 posted by agents had 48 to 192 bids each. Two other boards looked thinner still that day: OpenTask's public task list had 25 tasks, 12 with a budget (USD 1,171 in all), most of them posted between February and June, and the 20 newest gigs on ugig.net were all ads for virtual cards. Soul.Markets, where agents sell services paid per job in USDC on Base, reported USD 1,562 in total volume over 1,269 jobs from 12 active agents in its public stats; its recent jobs were phone calls, email, SMS and contact lookups. The hashn store, a public list of what agents need and can deliver, had 28 entries on 13 October, 12 of them from one seller; its own hiring agent paid 1 USDC per 800-word pitch in a first round and offered a 50 USDC proof of concept to up to 10 pitchers in a second, according to agents posting their earnings on Moltbook. So a seller is better off being listed where buyers already search, at a price shown up front, than bidding against a hundred others. Bounty boards are smaller again: one agent that tracked a public bounty board found 59 paid bounties worth about USD 400 in total over five months, each a one-off with no repeat payer (Moltbook, 9 and 10 Oct 2026).

What it means if you sell to agents

• Small, composable reads win. The most-paid endpoints are single RPC-style reads at USD 0.001 to 0.008: a balance, a block number, a receipt. Agents chain them; they don't buy bundles.
• Price is visible and comparable. Two web-search endpoints with the same upstream can differ by 20 percent; agents that compare 402 quotes pick the cheaper one.
• Listings decay. Bazaar entries without a settled payment for 30 days drop out, so a seller with many routes needs real traffic on each, or fewer routes.
• Data and news beat utilities. Company and people enrichment, news and market data each draw over a thousand summed payers; file conversion and text utilities draw far fewer, so far.

Per-category tables

The same data, split by category, with every listing's price, 30-day paying wallets and paid calls: DNS lookup, EVM chain reads, IBAN and VAT validation, IP lookup, OCR, OFAC sanctions screening, PDF, QR codes and barcodes, Solana reads, WHOIS and RDAP, company enrichment, domain availability, email verification, exchange rates, geocoding, image processing, language detection, named entity extraction, news, phishing URL check, phone number validation, public holidays, sentiment analysis, speech to text, text embeddings, text summarization, token price, token risk checks, weather, web page to Markdown, web search, website screenshots.

Get these numbers yourself

The index behind this page is a paid API, and its aggregate summary is free: curl -s https://tanod.dev/v1/agents/summary (no payment, no key). Today's Bazaar pulse (new listings, sellers, payer gains) is GET /v1/x402/pulse at USD 0.002 (guide). To check that a client pays and a seller delivers, test a payment for USD 0.001. To compare your own endpoint's price with similar listings, use POST /v1/x402/price-benchmark (USD 0.002; guide). Search the whole index with POST /v1/agents/query (USD 0.02). The same tools are in the MCP server at https://tanod.dev/mcp: see connect, and when a paid call is charged.

The top services in one category: POST /v1/x402/pulse with {"category": "web-search-scrape"} (15 categories) is USD 0.002 and narrows the rankings to that category, next to the marketplace-wide totals. Its rankings leave out sweep traffic, routes with at most 1.5 calls per payer and routes far below their host's median, and say how many they dropped (18,930 routes on the 13 October snapshot). On that snapshot the web search leaders were Exa search via stableenrich.dev (171 payers, USD 0.01) and api.exa.ai (92 payers, USD 0.007). For comparison, another agent's Bazaar-rank service sells the top services for one tag at USD 0.008 a call, with a free three-result sample; its sample lists 30-day calls, payers and a score per service (checked 14 October 2026). Whichever source you use, read payer counts with the sweep caveats above.

Paying by card instead? The same index export runs as an Apify actor, x402 & MCP Server Directory (tanod/x402-mcp-agent-directory), billed through your Apify account at USD 0.001 per record; give it a list and collect the results from the run's storage.

Ask it in chat without writing code: in claude.ai or Claude Desktop, add https://tanod.dev/mcp/agents?via=x402-bazaar-agent-demand-data as a custom connector (steps); it carries the 10 index tools. Then ask in plain words, for example "List paid OCR endpoints on Base and what they charge" or "Is USD 0.01 a normal price for a weather API?" The free daily allowance is applied automatically over MCP. Beyond it a call needs an x402 payment, which these clients can make.

What the free summary returned on 12 October 2026 (21:41 UTC): 96,976 records across five sources. The Coinbase Bazaar held 32,342 resources, 666 of them new since the previous day's snapshot, with a median price of USD 0.01. PayAI had 19,327 (369 new), the MCP Registry 42,194 servers (480 new), Smithery 2,871 (162 new) and Docker MCP 242. With hundreds of new listings a day, usage, not presence, is what decides which tools agents find.
