As of 2026-08-15, 37-27-249-33.sslip.io/builds on Base responded to 72.7% of 417 reliability checks since first seen 2026-08-01 (14 days), often enough to use but with outages frequent enough to plan around. Responses came back sluggish at 643 ms average from a single EU vantage point (so this includes network distance to the endpoint) and it has held its advertised price steady at $3.00. Its x402-trust grade is C (score 55.0 from a solid sample, tracked for 14 days), so it is best avoided for now.
Compiles a JSON product requirements document into an installable Android APK. Plans a design, generates the Flutter widget tree, wires Riverpod state into it, runs static analysis with an automatic repair loop, then packages the build. Returns a job id to poll, the APK, and the diagnostics if a build fails. Typically 5-8 minutes. MCP server at /mcp (JSON-RPC over HTTP, nothing to install) exposing validate_prd, prd_schema, payment_terms and build_status. FREE: POST /validate reports exactly what your document would build, using the same validator as the paid path, so anything it accepts will(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)
POST /v1/x402-trust or the x402_trust_score MCP tool.Latency is measured from a single EU vantage point; includes network round-trip distance to the endpoint; a geographically distant endpoint reads slower even when its server is fast, so it is only lightly weighted in the score.
10 better-scored and cheaper endpoints serving a semantically similar purpose exist.
We don't reveal which ones here. The ranked list (resource URLs, exact scores, prices & similarity, etc...) is one paid call away. Purchase it right here with a browser wallet, no code required:
A wallet payment page opens first; approve the USDC payment and the ranked JSON list loads right in your browser. Agents use the x402_find_alternatives MCP tool or POST /v1/similar directly.

- ✓Live probe at decision time:
We re-check the endpoint the moment you ask (timestamped) and compute the score from all scores up until this moment, instead of this cached snapshot that may be up to 24h old. - ✓Confidence band, full component breakdown & structured risk flags:
Exactly why the score is what it is, machine-readable. - ✓On-chain settlement proof:
Real USDC volume & distinct-payer count for the payTo wallet: is anyone actually paying it? - ✓90-day raw history:
Every listing/price/payTo change and probe result (viaPOST /v1/x402-history), up to 90 days back. - ✓The ranked better-scored alternatives:
The resource URLs, scores & prices we don't reveal above (viaPOST /v1/similar), if there are better alternatives available. - ✓Change & liveness alerts:
Get notified on payTo/price changes, spec regressions or downtime (viaPOST /v1/watch-endpoint-30d). Connect up to 10 Discord / Slack webhooks or poll regularly with bearer auth. Increases probe-density to every 5 minutes instead of the usual 30 for the watched endpoint.
