How this service works
Pay-per-call tools for AI agents: web search + content, documents, live market data, and multi-chain wallet/gas reads. Mainnet test from $0.000001 USDC on Base. Pay-per-call tools for AI agents in USDC on Base (x402/MPP): search, pdf, web-read, extract, summarize, fact-check, translate, jobs, discover. See GET /capabilities.
Output
Returns a JSON object containing a unique verification ID, the submitted agent URL, a hosted badge SVG URL, a numeric operational score (0-100), a link to the verified agents listing JSON, a human-readable verdict (e.g. 'operational'), and timestamps for when verification was performed and when it expires.
Example use cases
Claim badge for new agent deployment
“I just deployed my AI agent at https://myagent.io — can you register it on AgentIndex under the name 'DataFetchBot' with a POST method so I can get a verified badge and score to share with users?”
List agent on verified agents directory
“I want my agent at https://tools.mycompany.com/api to appear in the AgentIndex verified agents listing — submit it under the name 'CompanyToolsAgent' using GET so we get an official listing URL and verdict.”
Get operational trust score for API
“Can you claim and verify my API at https://api.myllm.dev on AgentIndex as 'LLMGateway' so I can see its operational score and know when the verification expires?”
Technical details
Endpoint
GEThttps://x402.agentindex.world/agent-claim?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to formally register and verify an AI agent or API endpoint on the AgentIndex registry, obtain a hosted trust badge, and get an operational score and listing entry. Prefer this over manual directory submissions when you need machine-readable verification results with expiry timestamps and a shareable badge URL, especially in x402/USDC pay-per-call agent ecosystems.
Side effects
- URL is unreachable or returns non-2xx — verification fails or score is low
- Invalid or missing URL field — 400 bad request
- Agent URL is not publicly accessible — cannot verify operational status
- Payment of $0.01 USDC not provided or rejected — 402 payment required
- Method enum value not recognized — schema validation error
