VIN decode API prices for agents
Snapshot 2026-10-07
A Vehicle Identification Number such as 1HGCM82633A004352 packs the make, model year, plant and body into 17 characters, but turning those characters into “a 2003 Honda Accord EX-V6 coupe” means looking them up against the manufacturer data the US government keeps in the NHTSA vPIC database. An agent handling a listing, a title or an insurance record wants that structured answer, and on the x402 marketplace it is sold per call. This page counts only endpoints whose job is to take a 17-character VIN and return the vehicle’s attributes — make, model, year, trim, body, engine, fuel, plant. It leaves out the neighbours that share the letters: VIN check-digit validators and WMI structure decoders that say whether a VIN is well formed without naming the car, and vehicle-recall lookups that take a make, model and year rather than a VIN. After that hand check, 11 priced offers remain on 2026-10-07, across 11 hosts. They list from USD 0.002 at the floor to USD 0.01 at the top, a USD 0.005 median. Tanod’s /v1/vehicle/vin-decode lists at USD 0.002.
Median listed x402 price to decode a VIN into make, model, year and attributes: USD 0.005 per call across 11 offers (snapshot 2026-10-07), from USD 0.002 at the floor to USD 0.01 at the top, with the middle half between about USD 0.003 and USD 0.005. Tanod’s route (/v1/vehicle/vin-decode) lists at USD 0.002, at the market floor: none is cheaper, one matches it, and ten cost more. The caveat worth stating up front: nearly every one of these endpoints, Tanod’s included, is a thin wrapper over the same free NHTSA vPIC database, so the honest edge is no-account per-call access and validation before you pay, not exclusive data.
The numbers
| Offers (not Tanod) | Floor | 25th pct | Median | 75th pct | Top | Tanod |
|---|---|---|---|---|---|---|
| 11 | USD 0.002 | USD 0.003 | USD 0.005 | USD 0.005 | USD 0.01 | USD 0.002 |
Eleven offers across eleven distinct hosts. Tanod’s USD 0.002 sits at the floor, below the USD 0.005 median. No competitor is cheaper; one matches Tanod at USD 0.002; ten list higher, up to USD 0.01, a fivefold spread for the same underlying government lookup. Each host counts once, so the count is not padded by one seller listing the same tool many times.

Prices are per call as listed, in USD; the six rows sum to 11. The bulk sits between USD 0.003 and USD 0.005, which is where the effort honestly lands: one HTTPS call to NHTSA’s free vPIC endpoint, parsed and returned. The USD 0.006 and USD 0.01 listings price above that; the dearest adds original factory pricing and fetch provenance, but the decode itself is the same public call.
Which listings agents actually pay
For most niches the Bazaar reports, per listing, how many distinct wallets paid it and how many paid calls it served in the last 30 days. For these eleven VIN decoders the 2026-10-07 snapshot carries no such counts — the demand field is empty for every one — so there is no reliable paid-usage ranking to show here, and inventing one would be dishonest. The market-wide demand picture, for the categories where counts do exist, is in x402 Bazaar agent demand data.
Every offer in the group
All eleven offers, across the price range and eleven distinct hosts. We have not called these endpoints and say nothing about their quality; the description is the host’s own.

Method
- Source: Tanod’s agent index of the CDP x402 Bazaar, latest ok snapshot 2026-10-07. Internal-only sources are not used. The MCP registry and Smithery carry no per-call price and are left out.
- Category: an endpoint whose job is to take a 17-character VIN and return the vehicle’s attributes — make, model, year, trim, body, engine, fuel, plant. Tanod’s own listing (tanod.dev) is excluded.
- Hand check: the letters “vin” and the word “vehicle” match many more hosts than decode this VIN, so each candidate was read and the neighbours removed by hand. Left out: VIN check-digit validators and WMI structure decoders that say whether a VIN is well formed or who the manufacturer is without naming the model (agentindex.world’s validate/vin at USD 0.002, aventtech’s ISO-3779 validate/vin at USD 0.01, alienprobe’s offline WMI-snapshot lookup at USD 0.005); vehicle safety-recall lookups, a separate niche keyed on make, model and year rather than a VIN (agent402, vextorium, macaroonnetwork, twin.unykorn and others all list one, and Tanod offers its own recalls route alongside the decoder); and keyword false matches (Vincenty geodesic distance, savings plans, Spanish fuel-price feeds and the like).
- Deduplicated: the same host counts once, at the price of its cheapest in-niche endpoint. forgemesh lists four VIN-decode routes (decode, lookup, decoder, decode-vin) all at USD 0.005; the railway host lists a single decode at USD 0.005 and a 25-VIN batch at USD 0.02; vextorium lists the decoder under both a Spanish and an English path at USD 0.003; each host was counted a single time, on its cheapest decode offer.
- The manual step is a judgement call and another reader could draw the line differently, especially over whether the WMI structure decoders count as decoding. The floor and median move little either way, but the count would change. Listed price is the first payment requirement the gate charges. Listings can be stale or wrong. Because the hand step is needed here, this page is the reference figure and this category is not in the automatic daily file x402-category-prices.json.
Tanod’s VIN decode route
One endpoint covers this niche, paid per call in USDC on Base, Polygon or Solana with x402. There is no account and no key; an unpaid call returns a 402 with the payment requirements. Price and behaviour are from Tanod’s configuration on 2026-10-11.
| What it does | Route | Price per call (USD) |
|---|---|---|
Decode a 17-character VIN into make, model, model_year, trim, series, body_class, doors, drive_type, transmission, an engine object (model, cylinders, displacement, horsepower, configuration), fuel_type, a plant object (country, state, city), manufacturer, vehicle_type and gvwr, plus the NHTSA error code and the North American check_digit_valid flag. The data is the US government’s NHTSA vPIC database (public domain). The VIN’s shape and check digit are tested offline before payment: a wrong length or character is a 422 and is never charged, and a wrong check digit is only a warning (non-North-American VINs can fail it legitimately). The only outbound hosts are NHTSA’s own; a NHTSA outage or timeout is a 503 that is never settled. Decodes are cached for 7 days. | /v1/vehicle/vin-decode | 0.002 |
This is an MCP tool too: decode_vin at https://tanod.dev/mcp, where the free tier is automatic. There are 10 free calls per IP per UTC day with the header X-Tanod-Free: 1; the pool is shared with the other utility routes (FX rates, QR codes, geocoding, validation and the rest). A companion route, /v1/vehicle/recalls, returns the NHTSA safety recalls for a make, model and year or for a decoded VIN.
Reading the comparison
- On price, Tanod’s USD 0.002 sits at the market floor. No competitor is cheaper, one matches it, and ten cost more, up to USD 0.01. Tanod is tied-cheapest rather than uniquely cheapest, so the price argument is that it is never the thing you overpay for, not that it beats every peer.
- The honest caveat: ten of the eleven listings name NHTSA vPIC, and Tanod reads it too. vPIC is a free, public US-government API with no key, so an agent that can make an HTTPS call can decode a VIN at no cost by calling it directly. The paid value exists for an agent that wants one metered, no-account call rather than carrying the integration, and that wants the VIN’s shape and check digit tested before any charge.
- What Tanod adds over a raw vPIC call is the validation-before-payment (a malformed VIN is rejected as a 422 and never billed), the no-settlement-on-outage rule (a NHTSA failure is a 503, not a charged empty answer), the structured engine and plant objects, and the shared no-account toolkit. It does not add data vPIC lacks.
- On breadth, Tanod decodes a single VIN per call. The railway host offers a 25-VIN batch at USD 0.02 for bulk work, and vindexapi adds original factory pricing and fetch provenance that Tanod does not carry. If you need batch decoding or MSRP history, those are the better fit.
- The data is US-market: vPIC is strong on vehicles sold in the United States and thin or empty on those that never were, a limit Tanod shares with every vPIC-backed peer here. The argument for Tanod is that the decoder sits in one no-account toolkit, on one USDC balance shared with sixty-odd other chain, document, image and web routes, at the market floor with a real free tier for low volume, with input validated before you pay and a recalls route alongside it.
