{"id":"6ae8b7f9-d07","name":"P0 Agent Economy Index — in-onchain","description":"Highest-demand x402 services tagged 'onchain': ranked by 30-day unique paying wallets, with calls, price, network and calls-per-payer for each. 165 providers and 235 paying wallets measured in this tag.. Computed from a full re-fetch of the Coinbase x402 Bazaar discovery feed (30-day window as published per resource), with a receipt naming the snapshot hash and generation time in every response. A paid call with no parameters at all returns data rather than an error, so a blind purchase is never wasted. Priced at $0.002 per call. Pays to a single address on Base, Arbitrum or Polygon; a plain USDC, USDT, DAI or native ETH transfer also works, as do Bitcoin and TRON — call the route again within 30 minutes or pass the transaction id.","endpoint_url":"https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-onchain","endpoint_canonical":"https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-onchain","category":"data.markets","kind":"api","price_amount":0.032,"price_currency":"USDC","chains":["base"],"request_schema":null,"response_schema":null,"sample_query":"https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/sample","facilitator_url":null,"status":"verified","delisted_reason":null,"origin":"claimed","ephemeral":false,"created_at":1789735956,"updated_at":1793081799,"status_changed_at":1793081799,"embedding_synced_at":1791913484,"score":0.9999999999996716,"p50_latency_ms":2665,"p95_latency_ms":4174,"p99_latency_ms":5127,"probe_count":737,"probes_passed":721,"last_ok_at":1794018416,"consecutive_failures":0,"last_probed_at":1794018416,"probe_interval_s":7200,"distinct_payers":0,"x402_version":2,"transport":"header","obs_scheme":"exact","accepts_count":9,"accepts_index":0,"obs_network":"eip155:8453","obs_asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","obs_pay_to":"0xECa891e34b3E5873181Fb779672564E198C55354","amount_atomic":"32000","amount_usd":0.032,"domain_name":"USD Coin","domain_version":"2","observed_at":1794018416,"obs_first_seen_at":1789736050,"price_changed_at":1791152085,"pay_to_changed_at":null,"payto_unstable":false,"payto_distinct_recent":1,"onchain_provider_status":null,"onchain_payto_checked":"0xeca891e34b3e5873181fb779672564e198c55354","onchain_checked_at":1794018995,"onchain_last_attempt_at":1794018995,"onchain_provider_error":0,"onchain_source":"index","header_bytes":14168,"verified_via":"GET","testnet":false,"payment_protocols":["x402","mpp"],"mpp_methods":["evm"],"mpp_offers":[{"method":"evm","intent":"charge","amount":"32000","currency":"0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85","recipient":"0xECa891e34b3E5873181Fb779672564E198C55354","chain_id":10,"realm":"x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev"},{"method":"evm","intent":"charge","amount":"32000","currency":"0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359","recipient":"0xECa891e34b3E5873181Fb779672564E198C55354","chain_id":137,"realm":"x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev"},{"method":"evm","intent":"charge","amount":"32000","currency":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","recipient":"0xECa891e34b3E5873181Fb779672564E198C55354","chain_id":8453,"realm":"x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev"},{"method":"evm","intent":"charge","amount":"32000","currency":"0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48","recipient":"0xECa891e34b3E5873181Fb779672564E198C55354","chain_id":1,"realm":"x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev"},{"method":"evm","intent":"charge","amount":"32000","currency":"0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E","recipient":"0xECa891e34b3E5873181Fb779672564E198C55354","chain_id":43114,"realm":"x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev"},{"method":"evm","intent":"charge","amount":"32000","currency":"0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9","recipient":"0xECa891e34b3E5873181Fb779672564E198C55354","chain_id":42161,"realm":"x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev"},{"method":"evm","intent":"charge","amount":"32000","currency":"0xaf88d065e77c8cC2239327C5EDb3A432268e5831","recipient":"0xECa891e34b3E5873181Fb779672564E198C55354","chain_id":42161,"realm":"x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev"},{"method":"evm","intent":"charge","amount":"32000","currency":"0xcebA9300f2b948710d2653dD7B07f33A8B32118C","recipient":"0xECa891e34b3E5873181Fb779672564E198C55354","chain_id":42220,"realm":"x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev"}],"mpp_note":"This endpoint's 402 also offers payment over MPP (the \"Payment\" HTTP authentication scheme): evm, as the endpoint names them.
