payment-ready 2026-08-04, probe currently failing

imported from the x402 Bazaar, not submitted by the operator · own this service? claim it · or ask to be removed

Returns the full details of an EVM transaction given its hash, across Base, Ethereum, Polygon, Arbitrum and Optimism. Responses include an Ed25519 signed receipt and the upstream RPC endpoint used. The first 3 calls per wallet are free via the X-WALLET header.

Pay from $0.003 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

ASSESSMENT

updated 4h ago

Evidence-backed signals, not a single score. Click any chip for the proof. Measured values stay read-only; unknown is honest.

reliability 91.6%

uptime 24h: 0%
uptime 7d: 0%
uptime 30d: 91.6%
uptime 90d: 91.6%
response p95: 1757ms

total checks: 1,374

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance A (14/14), stale (probe failing)

14 of 14 x402 conformance checks pass. Full checklist below.

risk clean

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Identity facts, not a risk score.

traction ---

This service shares a payout address and its probe has been failing, so its on-chain volume is suppressed until it responds again. Settlements on a shared address while a member is down are not attributed to it.

OVER TIME

All charts use the 7d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/synthora-rpc-transaction-by-hash/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
