Upstream API error — payment hash released for retry
All calls use the x402 payment protocol: send a request, receive a 402 with payment instructions, send USDC on Base L2, then re-call with the transaction hash.
GET https://gateflow-proxy.7crypto-jo.workers.dev/v1/a072c723/chain-tvl-rankings — receive a 402 with payment instructions
Send USDC on Base L2 to the address in X-Payment-Address
Wait for 1+ block confirmation (≈ 2 seconds on Base)
Re-send your original request with the tx hash in X-Payment-Hash
Obolo verifies on-chain and proxies the request to the upstream API
AP2 Support
This endpoint also accepts AP2 Cart Mandates. Include a signed Cart Mandate in the X-AP2-Mandate header with an x402 tx hash embedded in payment.txHash.
