OpenBlock Labs

OpenBlock Labs builds OB-1, a self-improving autonomous coding agent that automates the software development lifecycle from PM to PR. OB-1 runs as a native terminal CLI and inside VS Code and JetBrains IDEs, consumes MCP (Model Context Protocol) servers for custom tool integration, and provides a built-in browser agent. It routes across 300+ models via OpenRouter with bring-your-own-keys, bills usage-based at 1:1 model-token pass-through, and integrates with GitHub, Linear, Graphite, and Slack. Access is authenticated through a standards-compliant OAuth 2.0 / OpenID Connect authorization server (auth.openblocklabs.com, WorkOS AuthKit), with SSO/SAML, self-hosting, and audit logging available on enterprise plans. Originally surfaced as a portfolio company of Electric Capital and enriched by the API Evangelist pipeline from its public product surface and published auth metadata.

OpenBlock Labs is listed with 1 API on the APIs.io network. Tagged areas include Company, Data, Coding Agents, AI Agents, and Developer Tools.

OpenBlock Labs’ developer surface includes documentation, pricing, signup flow, support, authentication, CLI, and 11 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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)

11 more unmet checks in the Agent Readiness table above.

Developer Ergonomics scores 33.3 — up to +13.3 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/openblock-labs/apis.yml: open an issue on github.com/api-evangelist/openblock-labs to ask a question or point us at an artifact you publish.

Standards implemented 2

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.
