PLEXUS Intelligence API
https://plexus-public-production.up.railway.app/163 pay-per-call x402 endpoints: US federal regulatory data (EPA, SEC, FEC, OSHA, FDA, CourtListener, Congress.gov, GLEIF, WorldBank, SAM.gov and 15+ more), 12 AI reasoning engines (Tribunal, WHETSTONE, POSTCOG, G-Score, Verify), and 5 composite intelligence products (Company Risk, Political Intel, Supply Chain Risk, Healthcare DDIL, Nonprofit Intel). Base + Solana mainnet. No API keys.
Paid verification
How it worksNo sponsored paid call yet.
Pay this endpoint once from your own wallet (Base USDC, up to $1.00) and we call it and record what came back. Your wallet pays the listed recipient directly; Agent Tools never holds funds. Sponsored checks prove delivery; they do not count as demand.
Quality grade
How grading works- ✓ Answers a real HTTP 402 challenge
- ✓ Publishes a /.well-known/x402 descriptor
- ✗ Payment address on record
- ✗ Settlement network declared
- ✗ Price declared
x402 readiness
Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 53.3/100), which weighs availability, payability and on-chain demand. How the two differ
| Valid payment requirements | 0/10 | No payment requirements on record. |
| Live 402 challenge | 25/25 | Paid endpoint answers with an HTTP 402 challenge (138 ms). |
| x402 version | n/a | x402 version not observed yet. |
| Signed descriptor | n/a | No x402 standard defines a signed descriptor. |
| Uptime (30 days) | 15/15 | 23/23 probes succeeded over 30 days (100%). |
| Resource declaration | 10/10 | Declares 460 paid resource(s). |
| Verified identity | 5/10 | Publisher descriptor (/.well-known/x402 or OpenAPI) on record; claim this listing to verify domain control. |
| Freshness + modern flags | 5/5 | seen in a source within 7 days; declares x402. |
| Security declaration | n/a | Payment is the access control for an x402 resource. |
