How this service works
Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.
Output
A JSON object containing the search query, total count of matched providers, source URL, timestamp, and an array of results. Each result includes the provider ID, API title, preferred version, OpenAPI spec URL, description, categories, openapiVersion, and added/updated timestamps.
Example use cases
Discover Stripe's public API specs
“Search the APIs.guru directory for 'stripe' and give me the OpenAPI spec URLs and version info for their APIs.”
Find API categories for a cloud provider
“Look up 'googleapis' in the APIs.guru catalogue and tell me what APIs they have listed, including categories and descriptions.”
Locate OpenAPI spec for a fintech provider
“I need the OpenAPI spec URL for 1forge — can you check the APIs.guru directory for '1forge' and return the spec link and preferred version?”
Technical details
Endpoint
GEThttps://api.companyrecords-api.workers.dev/api/b2b/apis-guru-openapi-directory?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover OpenAPI/Swagger specification URLs and metadata for known API providers by domain name. It is ideal for agent workflows that need to fetch a spec before calling or analyzing an API. Prefer it over scraping APIs.guru directly since this wrapper is a paid-access, agent-friendly JSON API. Not suitable for searching by category or keyword without a domain name hint.
Side effects
- Query string shorter than 2 or longer than 60 characters returns a validation error
- No matching providers returns an empty results array with count 0
- Provider exists in APIs.guru but has not been indexed recently, so data may be stale
- Limit parameter out of range (must be 1–25) may return an error or be clamped
- Upstream APIs.guru service unavailable causes a proxy error
