Story Protocol

Story Protocol is a purpose-built EVM Layer 1 blockchain for onchain intellectual property (the "IP blockchain"), powered by Proof of Creativity, built by Pip Labs and backed by a16z. Its public REST API (api.storyapis.com) is a read-only indexer that exposes IP assets, collections, license terms, license templates and tokens, minting fees, disputes, IP groups, royalties, protocol modules, permissions, and transactions across Story mainnet (chain 1514) and the Aeneid testnet (chain 1315). Authentication is an X-Api-Key header plus an X-Chain network selector; official TypeScript and Python SDKs wrap both the API and the onchain protocol.

Story Protocol publishes 13 API contracts indexed on the APIs.io network, including Collections API, Disputes API, IPAssets API, and 10 more. Tagged areas include Company, Blockchain, Intellectual Property, Licensing, and Royalties.

The Story Protocol catalog on APIs.io includes 1 Spectral governance ruleset.

Story Protocol’s developer surface includes documentation, API reference, getting-started guide, authentication, changelog, sandbox, and 18 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

10 more unmet checks in the Agent Readiness table above.
