Secant Agent Research Pack

- search: ranked web search.
- research_pack: search, selected page extraction, normalized JSON, and citations.
- extract_page: readable page text and metadata extraction.
- monitor_diff: page change checks.

All tools use the same retry-safe x402 pattern:
- Call the tool withoutpaymentto receive the upstream payment requirement.
- Pay the quoted Base USDC requirement with an x402-compatible client.
- Retry with the payment proof and, when available, the samepayment_identifier.

The wrapper returnspayment_required: trueand the upstream 402 body for unpaid calls. It does not execute paid work until the live API accepts the payment proof.

The native paid API uses HTTP402and Base USDC over x402. If you call a tool without a payment proof, the tool returns the upstream payment requirement so an agent can pay and retry. If you include a valid payment proof, the tool forwards it to the live API.
