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 APIs 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 authentication, GitHub presence, and 18 more developer resources.

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.

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.
