Research / one complete agent job
Ask now.
Know what came back.
Research returns current evidence with its sources inside one explicit cost boundary. The first call needs no account, no key and no wallet.
The whole job / one command
This is the entire integration.
No account, no key, no wallet. The free route currently requires an idempotency-key header, so the command below carries one; reuse the same value to replay without a second execution.
curl -sS https://api.clervo.dev/v1/search/free \
-H 'content-type: application/json' \
-d '{"query":"what is the x402 payment protocol","maxResults":3,"synthesize":false}' \
-H 'idempotency-key: clervo-first-call-0001'What comes back
Evidence you can check, not prose you must trust.
Ranked evidence
Normalized retrieval results in a stable shape, ordered by relevance rather than by whoever paid for placement.
Source citations
Every result carries the source it came from, so the answer can be checked rather than trusted.
No synthesized prose
The publicly available operation returns evidence, not an essay. Synthesis is a separate operation and is not publicly available.
A bounded cost
The maximum charge is quoted before anything runs, and the settled amount is never higher.
What it costs

What has been paid for
One settlement, one useful result, one safe replay.
The owner funded this to verify payment plumbing. It is not a customer transaction, and no revenue, demand or public commercial traction follows from it.
