FluentEDI

45 deterministic tools for AI agents, free and with no API key, signup or rate limit. Every tool is a single stateless GET or POST returning JSON, read-only and idempotent. Coverage runs deepest in retail EDI -- X12 850/856/810/855/997 parsing, generating an 856 with correct HL parent pointers and a fixed-width 106-character ISA, envelope validation, decoding a 997 acknowledgment into plain language, and GS1 check digits -- alongside timezone and delivery-window arithmetic, cron, exact maths, JSON repair with line/column error localisation, JSONPath, RFC 8785 canonical JSON with CIDv1, Ed25519/ECDSA/RSA signature verification, secret and PII scanning, link-liveness checking with retraction detection, endpoint assertion, and text position conversion.

FluentEDI publishes 10 API contracts indexed on the APIs.io network, including Compute API, Crypto API, Data API, and 7 more. Tagged areas include EDI, X12, Retail EDI, AI Agents, and MCP.

FluentEDI’s developer surface includes pricing, authentication, GitHub presence, and 19 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/fluentedi: open an issue to ask a question, or submit a pull request to add artifacts.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
