What phishing URL check APIs cost over x402
Snapshot 2026-10-10
An agent can send a URL or domain to an endpoint that says whether it is phishing or malicious and pay for the call over x402. We index the x402 Bazaar and PayAI daily, so here is what those listings charge on 2026-10-10. The short version: we found 22 distinct priced offers that check a URL or domain for phishing or malware, on 19 hosts. The median is USD 0.01 per call, the lowest is USD 0.002 and the highest USD 0.15. Tanod charges USD 0.001 per call, which is below every listing: 0 are lower, 0 list the same and 22 are higher. The comparison is not like for like. Tanod answers one question, whether the host is on two public phishing and scam domain lists, and does not score the URL; most listings score the text of the URL, a domain's registration age, DNS or certificate, or look it up in other lists (five name URLhaus, one names GoPlus). Tanod also has a batch route; only one listing, a domain risk report for up to 20 domains per call, is a batch. These are listed prices, matched by keyword and reviewed by name and description; we have not tested the endpoints or compared their detection.
Median listed x402 price for phishing URL checks: USD 0.01 per call across 22 offers on 19 hosts (snapshot 2026-10-10). Tanod: USD 0.001 per call (below every listing).

Prices are per call as listed, in USD, not a measure of detection quality or uptime. Where listings name a method, three score the URL text with heuristics only (one of them says it never returns a clean verdict because it consults no threat database), five name the abuse.ch URLhaus malware list, one the GoPlus phishing database, and twelve read domain age, registration, DNS or certificate data (some of these overlap). None names the two lists Tanod uses.

All offers found, ordered by price. The last column paraphrases the listing text; we have not called these endpoints and say nothing about their detection rate.
| Host and path | Listed price (USD) | What the listing says |
|---|---|---|
402.com.tr/api/x402/url-risk | 0.002 | heuristic URL risk (scheme, IP hosts, deep subdomains, credential-themed labels, sensitive paths, optional brand lookalike) with reasons and a GO, HOLD or STOP; says it is not a malware or Safe Browsing scan (GET with a query string) |
apexfaucet.xyz/api/x402/domain-check | 0.002 | phishing domain check from domain age and registrar (RDAP), DNS, TLS certificate and lookalikes of 40 brands; an unreadable record is reported as unread, never as clean (GET with a query string) |
api.vextorium.com/v1/malicious-url | 0.002 | whether a URL or domain is in abuse.ch URLhaus as a malware distribution site in the last 30 days, with threat type, online status and date; a second route on the same host is the same service in Spanish, counted once |
safe.cyberwarex.com/check | 0.003 | phishing risk score 0 to 100 and a SAFE, SUSPICIOUS or DANGEROUS verdict from keyless heuristics (brand typosquats and homoglyphs, punycode, credentials in the URL, raw IPs, suspicious TLDs, deep subdomains) plus a best-effort domain-age check |
url-oracle.fly.dev/verify | 0.003 | ALLOW, WARN or BLOCK verdict: typosquatted or phantom-squatted brand domains, unregistered or new domains, and known malicious infrastructure from URLhaus |
tools.halowerk.com/v1/url/risk | 0.004 | German listing: redirect chain with a record of each hop, punycode and homograph flags, certificate, domain age, registrar, nameservers, ASN and hosting, open blocklists and DNSBL for the target IP, and a scan of the page text for hidden instructions to language models |
urltrust.openverbs.com/v1/analyze | 0.004 | phishing score 0 to 100 and verdict from offline lexical and structural heuristics with no network lookups: raw-IP hosts, embedded credentials, punycode, brand typosquats, abused TLDs, shorteners, odd ports |
agent.pocket.network/v1/url-phishing-reputation | 0.005 | phishing signs without fetching the URL (raw IP, punycode, user@host, credential words, very long or deep hosts); the verdict is suspicious or unknown, never clean, because no threat database is consulted |
mcp.dropenginehq.com/api/check-url | 0.005 | URL safety preflight: syntax, host and IP, patterns, redirects and optional threat intelligence |
urltrust.openverbs.com/v1/domain | 0.006 | domain risk score 0 to 100 and verdict from RDAP registration age, DNS resolution, MX and DNSSEC, with reasons; the sibling route on the same host scores the URL text |
agentbit.app/v1/security/url-threat | 0.01 | risk score 0 to 100 with named flags from phishing-pattern heuristics, a server-side redirect trace with cross-host detection, and an optional URLhaus lookup; the listing says heuristics plus public threat data, not a sandbox |

agent402.tools/api/skill/brand-protection | 0.018 | domain legitimacy check that runs four tools in one payment (WHOIS age, DNS, a web search for scam and phishing reports, HTTP headers); partial success per step |
eltociear-skill-audit.hf.space/trust | 0.02 | scam, phishing and trust vetting of an x402 server or any URL: transport, content-safety, domain, metadata and x402-compliance sub-scores with evidence |
payai.agentstools.dev/domain/trust | 0.02 | phishing and trust verdict for a domain: registration age (RDAP), DNS and mail posture, TLS, Certificate Transparency history and a typosquat and homoglyph analysis fused into a score 0 to 100 and a category |

Method
- Source: Tanod's agent index of the x402 Bazaar and PayAI, queried 2026-10-10 (newest listing seen 2026-10-09T04:31:37Z), listings last seen on or after 2026-10-07. Internal-only sources, Circle-sourced rows and Tanod's own routes are not used.
- Match: listings with a price above zero whose URL, name or description combines URL, link, domain or site with phishing, malicious, scam, safety, risk, reputation or threat wording, or names URLhaus, Safe Browsing, malware or a blocklist. About 110 distinct URLs matched and were reviewed by name and description, and a second pass over URL, link and domain wording was read by path. Only endpoints that take a URL or domain and return a phishing, scam or malware verdict, score or list match were kept: 22 offers on 19 hosts.
- Excluded: smart-contract scanners and wallet or token address risk checks (for example
aayatai.com/wallet/risk, theapi.verdixapi.comroutes,api.anchor-x402.com/v1/screen,x402check.xyz/v1/risk-checkandpresign-guard.fizzl.eu/v1/check), package and agent-skill scanners, general domain reports and WHOIS-style lookups (x402.ottoai.services/domain-report,api.x402node.dev/domain/check,api.strale.io/x402/domain-reputation,402oracle.com/verify/business), email-authentication and IP-blocklist checks, redirect tracers (unwrap.use.x402atlas.com,1cent.maxzoa.ru/v1/url/redirects), typosquat-variant generators (intel.rallylive.ca/dns/typosquats), a type-agnostic threat-indicator route (api.agentstools.dev/threat/iocand its PayAI twin, which takes hashes, IPs and CVE ids as well), merchant trust scores, and three routes with no usable description that we could not classify:engedi.digi-life17.workers.dev/api/url-safety(listed at USD 0.001, with no description at all) andagents.daedalusdevelopmentgroup.com/v1/intel/url-reputationand/v1/intel/domain-reputation(placeholder text only). The first of these is listed at the same price as Tanod. A looser rule would find more, and a stricter one fewer. - Deduplicated by URL; near-duplicate routes on one host that the listing says share a backend are counted once (the Spanish route on
api.vextorium.com, the bulk and change-watch variants onintel.rallylive.ca, and listings that appear on both indexes). Hosts are counted by host name. Listed price is the first payment requirement; some endpoints may charge differently by input. Percentiles are linear interpolation between ranks. Median of 22 prices is the average of the 11th and 12th values (both 0.01).
Where Tanod fits
POST /v1/check/url takes a url or a domain (one of them, up to 2,048 characters; IP hosts are matched exactly). It normalises the host and matches it, then its parent domains up to the registrable domain (Public Suffix List), against two public lists, PhishDestroy (CC0) and Phishing.Database (MIT), refreshed daily. It returns listed, the matched_domain, the sources that list it, shared_platform, list_updated_at and a disclaimer. Entries naming large shared platforms and link shorteners (for example bit.ly or sites.google.com) are ignored, so only a listed subdomain on such a platform matches. A host that is not listed is not cleared: new or targeted phishing is on no list yet, and lists can hold stale or mistaken entries. The URL is only parsed, never fetched, so there is no redirect following, no domain age, no certificate, lookalike or page-content check, and no score. Input that is not a URL, host or domain is a 422 that is not charged. It typically answers in under 0.1 s (up to a few seconds on the first call). POST /v1/check/url/batch takes 1 to 1,000 items, returns a result per item and a listed_count, and fails the whole batch with a 422 naming the item if one is invalid (not charged). The single check costs USD 0.001 per call; the batch costs USD 0.0002 per item, at least USD 0.001 per call, so 20 items cost USD 0.004 and 1,000 items USD 0.2. Payment is in USDC on Base or Polygon with x402. 10 free calls per IP per UTC day apply to the single check only, shared with the other chainpeek reads and the single sanctions screen; the batch has no free tier. The MCP tools are check_url_phishing and check_urls_phishing_batch at https://tanod.dev/mcp. Details are in the phishing URL checker guide.
When a priced listing above is the better choice
- You need a verdict on a domain that no list has seen yet: most listings above score the URL text, domain age, DNS or certificate, which can flag a new lookalike. Tanod only reports a list match.
- You need the redirect chain followed or the page checked: four listings resolve redirects and one also audits headers and the certificate. Tanod never fetches the URL.
- You want domain registration data (age, registrar) with the verdict: nine listings return domain age.
- You want a crypto-specific phishing database such as GoPlus, which one listing names; we have not compared its coverage with the lists Tanod uses.
When Tanod fits
- You want the lowest listed price, USD 0.001 per call, below every listing found, with a free allowance for trying it.
- You screen many links: the batch takes up to 1,000 per call at USD 0.0002 each (at least USD 0.001); the one batch listing found takes 20 domains for USD 0.01.
- You want a plain list match with named, licensed sources, the list refresh time in every answer, and no network call to the target, with the submitted URLs not logged or stored.
