Payout address in review

The live 402 response asks to be paid at a different address than this listing shows. The change has not been reviewed yet, so this page and the API keep the previous address until it is. Check the address in the 402 response you receive before you pay.

POST/chain/checkToken safety check (rug check) for AI agents before buying, sending or accepting a crypto token on Base, Ethereum or Solana: give its address, get name, supply, live on-chain price and pool liquidity, plus contract controls (owner, upgradeable proxy, mint, pause, blacklist, fee setters) or Solana mint and freeze authority, with plain warnings. Facts read from the chain, not a rating.$0.004Base+SolUSDCheadersince 10-27

POST/chain/priceCrypto token price in USD for AI agents: give a token contract address or mint (or "SOL") on Base, Ethereum or Solana, get its live USD price read on-chain from the deepest DEX pool (Uniswap v3, Orca Whirlpools), not from a price API. Returns the pool used, its depth in USD and a low-liquidity flag, so a trading agent knows how far to trust the quote.$0.001Base+SolUSDCheadersince 10-27
POST/chain/pulseCrypto market overview in one call: Fear & Greed Index, BTC, ETH and SOL price, 24h change and funding, the highest and lowest funding rates, top gainers and losers, and Hyperliquid open interest.$0.003Base+SolUSDCheadersince 10-27

How the score works

What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 90ms response p95, x402 compliance 14 of 14, $0.001 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 88 listings, this one among them: the same 88 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

Crypto data for AI agents, paid per call in USDC on Base or Solana: crypto news with a mood read, Hyperliquid perps, a market pulse, Chainlink price history, token prices and safety checks, a pre-trade check, wallet balances and portfolios, and transaction lookups on Base, Ethereum and Solana. Failed calls are free.

Tollkit Chain is a listed x402 Blockchain API. Captured payment terms name Base, Solana. 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.

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.

Values

* today so far, partial (UTC).

The uptime summary counts completed UTC days only. The strip, readouts and table retain today's partial reading.

Daily snapshot total, 30d: $2.24, peak $0.41 on 10-04. 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: 2026-09-28 to 2026-10-27 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. † marks a recorded $0.00 with settlements.

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.
