pay_then_call

io.github.skewing1/insurelink · Verify this server

Wrap any paid HTTP endpoint in the x402 pay-then-call loop and return the downstream response plus an EIP-191 signed receipt proving InsureLink mediated the call. The signed context envelope contains: { request: {url, method, body_sha256}, payment: {asset, amount, network, settlement_id}, response: {status, sha256, content_type, length}, observed_at, mediator: 'insurelink' } and a signature recoverable to InsureLink's deployer key. Two modes: (a) caller_supplies_payment — pass `x_payment_header` (base64) so the upstream call is settled by your wallet; (b) `mode='quote_only'` — return only the 402 quote without paying. Pass `idempotency_key` to safely retry: identical requests return the cached signed receipt without settling a second payment, and conflicting payloads under the same key are rejected. Use this to give an LLM verifiable provenance for any paid agent call (banking, market data, gov endpoints).
