Example 402 response
Endpoints and prices
| Method | Path | Description | Price | Network | Asset | 402 channel | Captured |
|---|---|---|---|---|---|---|---|
| GET | / | ENS name resolution in both directions on Ethereum mainnet. Pass name to resolve an ENS name to its address (forward), or pass address to get that address's primary ENS name (reverse, forward-verified so spoofed reverse records are rejected). Read straight from the ENS registry. Use it to turn vitalik.eth into an address, or to label a raw address with a human-readable name. | $0.003 | Base | USDC | header | since 09-07 |
| GET | / | Live gas market on any major EVM chain: current gas price, base fee and priority-fee percentiles (p25/p50/p75) in gwei, plus the estimated cost in native token and USD for a plain transfer (21k gas) and a typical DEX swap (200k gas). Lets an agent decide whether a transaction is worth sending right now or should wait for cheaper gas, and budget the fee before signing. | $0.002 | Base | USDC | header | since 09-07 |
| GET | / | Spot USD price for any crypto asset. Accepts a ticker symbol (eth, btc, sol), a CoinGecko id (ethereum), or an EVM token contract address. Returns the USD price plus 24h change, with market cap for listed assets, or liquidity, 24h volume and the top DEX pair for contract addresses. Cached 60 seconds so repeated calls in one agent workflow stay consistent with each other. | $0.002 | Base | USDC | header | since 09-07 |
| GET | / | ERC-20 token profile on any major EVM chain: on-chain metadata (name, symbol, decimals, total supply) read straight from the contract, joined with live DEX market data (USD price, liquidity, 24h volume, 24h change, and the top trading pair with its DEX). Use it to price a token, check liquidity depth before a swap, or resolve an unknown contract address into a real token. | $0.004 | Base | USDC | header | since 09-07 |
| GET | / | Transaction lookup and decode on any major EVM chain. Turns a raw tx hash into agent-readable facts: success or failure status, block number, sender and recipient, native value transferred, gas used, fee in native token and USD, and every ERC-20 transfer decoded with token symbol, decimals and human-readable amount. Returns found=false for an unknown hash instead of erroring. | $0.003 | Base | USDC | header | since 09-07 |
| GET | / | Wallet snapshot on any major EVM chain: native token balance with USD value, USDC balance, transaction count (nonce), and whether the address is a smart contract or a regular EOA. One call, no RPC keys, node infrastructure or block-explorer scraping needed. Use it to check a counterparty wallet, confirm an address is funded before sending a transaction, or profile an unknown address. | $0.003 | Base | USDC | header | since 09-07 |

How the score works
What the score read on this service: status online, 99.5% uptime 30d, 422ms response p95, x402 compliance 14 of 14, $0.002 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.
The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.
Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.
It is a score inside Blockchain, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 75 listings, this one among them: the same 75 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.
Traction is a conservative undercount.
All measured facts
What it does
Pay-per-call EVM chain data for AI agents: wallet balances, token profiles with live DEX market data, spot prices, gas market, decoded transactions, ENS. Base, Ethereum, Arbitrum, Optimism, Polygon. No API keys or node infra - one x402 USDC micropayment per call ($0.002-0.004).
Onchain Query API is a listed x402 Blockchain API. Captured payment terms name Base. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.
Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.

The uptime summary counts completed UTC days only. The strip, readouts and table retain today's partial reading.
Daily snapshot total, no volume data in the last 30d. The visible 30d total in Traction comes from the latest assessment. These sources can differ in their window, refresh time, cent rounding and shared-address attribution.
Daily address snapshots: 2026-09-23 to 2026-10-22 UTC; * today so far, partial (UTC). Daily snapshots store cents. A recorded $0.00 with settlements cannot distinguish exact zero from volume rounded away. Lost precision is unavailable here.
Settlement volume uses the stored USD valuation of tracked payments; it is distinct from token quantities. USD-pegged assets are valued at 1 USD per token in these rollups. The measured settlement floor does not cover all payments to this service.
