POST/agent-fortuneAgent fortune API: a fortune cookie written specifically for AI agents ('A cached response is worth two upstream calls'), plus a lucky number and lucky HTTP status code. The cheapest, most delightful way to make your first x402 payment and verify your wallet stack works end to end. New fortune every call.$0.001BaseUSDCheadersince 07-20
POST/color-convertColor conversion API: any hex or rgb() color to hex, RGB, and HSL plus is-it-dark detection and the accessible text color (black or white) to place on top of it. For theming, chart, and design-generation agents. Instant, computed locally.$0.001BaseUSDCheadersince 07-20
POST/convert-timezoneTimezone converter API: convert a wall-clock time from one IANA timezone to another with daylight-saving applied correctly · returns converted local time, UTC ISO, and unix epoch. 'What is 3pm Tokyo for Chicago?' deterministically. For scheduling and calendar agents.$0.001BaseUSDCheadersince 07-20
POST/convert-unitsUnit conversion API: convert between 100+ units across length, mass, volume, temperature, area, speed, pressure, energy, power, and digital storage. Exact factors, instant, local. Deterministic and auditable · cheaper than burning reasoning tokens, zero arithmetic-hallucination risk, and the result can be cited. Unknown units return a helpful 400 listing valid targets.$0.001BaseUSDCheadersince 07-20
POST/hash-textText hashing API: SHA-256, SHA-512, SHA-1, or MD5 digest of any text, returned as hex · deterministic, instant, computed locally. For deduplication keys, cache keys, content fingerprints, and integrity checks in agent pipelines.$0.001BaseUSDCheadersince 07-20
POST/integer-trivia-lookupInteger trivia lookup: give any whole number and get back whether it's prime, its full prime factorization, whether it appears in the Fibonacci sequence, its binary and hexadecimal forms, Roman numeral equivalent, and digit sum, all computed exactly and instantly. A fun grab-bag for quiz bots, math-education tools, and number-curious agents.$0.001BaseUSDCheadersince 07-20
POST/number-factsNumber facts API: everything mathematically interesting about any integer · is it prime, its prime factorization, Fibonacci membership, perfect-square status, even/odd, binary and hexadecimal forms, Roman numeral, and digit sum. Computed locally, deterministic, instant. For quiz agents, content generation, validation, and the incurably curious.$0.001BaseUSDCheadersince 07-20
POST/percentage-calculatorPercentage calculator API: compute 'X% of Y', 'X is what percent of Y', percent change between two numbers, or increase/decrease a number by a percent · the everyday percentage math, done exactly.

POST/robinhood-chain-tokensRegistry of tokenized stock and ETF contracts on Robinhood Chain (chain id 4663): 25 verified token addresses with their on-chain price-feed addresses, chain metadata (RPC, explorer, gas token), and source citations for every entry. Read-only public blockchain data · informational only, no trading or brokerage functions.$0.001BaseUSDCheadersince 07-20
POST/text-statisticsText statistics API: characters, words, sentences, average sentence length, Flesch reading-ease score, estimated reading time, and estimated LLM token count for any text · instant, computed locally, nothing stored.

How the score works

What the score read on this service: status online, 100% uptime 30d, 461ms 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 Data, 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 386 listings, this one among them: the same 386 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.

Delivery-verified 2026-09-02 (paid probe delivered HTTP 200), no expiry, revoked only on payTo or schema drift. Settled via coinbase ($2.52, 229 tx). Traction is a conservative undercount; first settlement seen 2026-07-15.

All measured facts

What it does

Pay-per-call API grid from ForgeMesh Labs, about 415 POST endpoints for small agent tasks: unit and timezone conversion, reference lookups, text and number utilities, chess logic, and read-only Robinhood Chain token registry data. From $0.001 per call in USDC on Base.

ForgeMesh Utility APIs is a listed x402 Data 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.

Daily snapshot total, 30d: $2.40, peak $0.48 on 10-01. 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.
