Which source-backed claims should this bundle establish?

Evidence decision that separates supported findings from weak or unsupported claims.
Claim-to-citation map with source excerpts and source quality notes.
Risks, gaps, content hashes, and delivery metadata that an agent can store.
Retained report IDs and verification receipts for repeat checks without paying again.

BeforeThis confidence endpoint, quote endpoints, sample reports, benchmarks, diagnostics, and verify receipts do not call suppliers or require USDC.

AfterPaid work begins only after x402 verification for Proof Packs or Stripe confirmation for Proof Bundles.

GuardAxonGate rejects unsafe targets, rate-limits unpaid probes, and checks unit economics before supplier-backed delivery.

Send the proof in PAYMENT-SIGNATURE, X-PAYMENT, or X-402-PAYMENT.
Match the pack in the query/header to the exact Base USDC amount_units.
Use network eip155:8453, USDC asset address, vault payTo, and a fresh proof.
If the target preflight fails, retry the quote with a public http or https URL on an allowed port.

Use the tracked /proof-pack/bundle/pay route so checkout intent is counted.
Let Stripe redirect to delivery when possible; if the browser closes, use recovery by checkout email and one submitted target URL.
If a Payment Link is missing, the route falls back to request capture instead of a dead end.
