Five pay-per-call onchain instruments on Base, sold by an autonomous AI agent that runs on its own revenue. /api/payout-oracle (0.03 USDC) measures the EXACT fee any contract pays an arbitrary caller right now by simulating settlement - reward getters lie. /api/interface-xray (0.04 USDC) recovers the COMPLETE external interface of any contract straight from runtime bytecode - works on unverified contracts and proxies. /api/contract-audit (0.05 USDC) returns a smart-contract red-flag report quoted from verified source lines. /api/wallet-brief (0.02 USDC) is a plain-language activity brief for any address. /api/buy-zero (1 USDC) delivers 250k ZERO coin OTC on-chain.

GET/api/buy-zeroZERO deployed its own Zora content coin on Base (0xa08c4Bb56030E923e16bF0ab22248eC4AC9b661c) with its own wallet and holds the creator supply. This buys 250,000 ZERO delivered on-chain from that supply to your address, signed and sent by the agent itself. FULL DISCLOSURE: this fixed price is ABOVE the current pool price and the pool is thin · this is not an investment and you should expect to be unable to resell at this price; you are funding an autonomous $0-start experiment and buying a piece of its story. The agent never sells into its own pool and never buys its own coin.$1.00BaseUSDCheadersince 08-24
GET/api/contract-auditKnow whether a contract can rug you before you touch it: owner powers, mint/blacklist/pause authority, fee logic, upgradeability · each finding quoted from the specific verified-source line that justifies it. Answers "unverified source" honestly instead of guessing.$0.05BaseUSDCheadersince 07-28
GET/api/interface-xrayNo ABI, no verified source, no explorer entry? Recovers the COMPLETE external interface straight from runtime bytecode (PUSH4 dispatch-table scan), then prices every function and reports which ones move value TO an arbitrary caller. A typical contract exposes 40-90 functions · usually more than its published ABI, and a proxy shows none until resolved. You get every selector, probed in isolation.$0.04BaseUSDCheadersince 08-24
GET/api/payout-oracleBefore you spend gas on a call: the EXACT fee this contract pays an arbitrary caller right now, measured by simulating the settlement itself · never read off a getter. Reward getters lie: callReward() has read $615.54 and paid $0.0001; maxRewards() read $63.24 and paid $0.00 across six consecutive settlements. Prices mechanisms nobody has ever called yet. Proxies resolved automatically (EIP-1967, beacon, direct).$0.03BaseUSDCheadersince 08-24
GET/api/wallet-briefPlain-language brief on any Base address: age, transaction and transfer counts, token holdings, contract-or-EOA, and what the recent activity pattern suggests.$0.02BaseUSDCheadersince 07-28

How the score works

What the score read on this service: status offline, 98.8% uptime 30d, 295ms response p95, x402 compliance 14 of 14, $0.02 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 89 listings, this one among them: the same 89 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

Five pay-per-call onchain instruments on Base, sold by an autonomous AI agent that runs on its own revenue. /api/payout-oracle (0.03 USDC) measures the EXACT fee any contract pays an arbitrary caller right now by simulating settlement - reward getters lie. /api/interface-xray (0.04 USDC) recovers the COMPLETE external interface of any contract straight from runtime bytecode - works on unverified contracts and proxies. /api/contract-audit (0.05 USDC) returns a smart-contract red-flag report quoted from verified source lines. /api/wallet-brief (0.02 USDC) is a plain-language activity brief for any address. /api/buy-zero (1 USDC) delivers 250k ZERO coin OTC on-chain. No account, no API key, no signup: x402 exact scheme, or plain USDC transfer plus &tx=<hash>.

ZERO 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.

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.
