Example 402 response
Endpoints and prices
| Method | Path | Description | Price | Network | Asset | 402 channel | Captured |
|---|---|---|---|---|---|---|---|
| GET | / | Fast pre-payment sanity check for agents on Base: confirms the RPC reports Base mainnet (chain ID 8453) and that the official USDC contract has deployed code. No request body. Returns PASS or FAIL with both checks and a timestamp. It is not a token-risk report, transaction simulation or payment proof. | $0.001 | Base | USDC | header | since 09-28 |
| POST | / | Token-risk report for one Base ERC-20 contract. Checks whether the token can be sold (honeypot simulation), buy/sell/transfer tax, owner privileges (mint, pause, blacklist, balance changes, proxy upgrades), holder concentration and DEX liquidity. Returns ALLOW, WARN, BLOCK or INCOMPLETE with scored findings and per-check coverage. INCOMPLETE means required evidence was unavailable, never zero risk. Read-only: never signs or trades. | $0.001 | Base | USDC | header | since 09-21 |
| POST | / | Simulate one unsigned Base transaction before an agent signs it. Runs eth_call and gas estimation on current chain state, decodes the intent (ERC-20 transfer, approve, NFT setApprovalForAll), flags unlimited approvals, calldata sent to a non-contract, zero-address targets, reverts and destination risk labels such as phishing or sanctions. Returns ALLOW, WARN, BLOCK or INCOMPLETE with findings. No key or signed transaction is requested. | $0.001 | Base | USDC | header | since 09-21 |
| POST | / | Verify one Base USDC payment onchain before an agent releases goods or credit. Reads the transaction receipt and checks the official USDC Transfer logs against the expected recipient, amount and optional sender. Returns VERIFIED, MISMATCH, FAILED or PENDING_OR_NOT_FOUND with block number, confirmations, the matching transfer and a Basescan link. Read-only: never moves funds. | $0.00288 | Base | USDC | header | since 09-21 |

How the score works
What the score read on this service: status online, 100% uptime 30d, 261ms 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 Verification, 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 186 listings, this one among them: the same 186 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.
Settled via coinbase ($0.02, 13 tx) and payAI ($0.007, 7 tx). Traction is a conservative undercount; first settlement seen 2026-09-18.
All measured facts
What it does
KushBitx provides safety checks for AI agents that pay on Base, as pay-per-call x402 APIs in USDC. Token risk, unsigned transaction preflight and Quick Check (Base identity plus USDC contract-presence) cost 0.001 USDC per call; payment verification costs 0.00288 USDC. SpendGuard spend-policy checks are free. Also available as an MCP server at https://kushbitx.com/mcp. No signup or API keys. Missing evidence is reported as INCOMPLETE; automated screening is not a contract audit. We never hold keys, sign or move funds. https://kushbitx.com/pricing
KushBitx AgentProof is a listed x402 Verification 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.

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.
