The Otto X402 Router answers a question every x402 agent hits: which endpoint do I call for this? Send one request describing what you need, and the Router returns the best-matching x402 services — ranked across both Otto’s own verified catalog and the live, public CDP Bazaar — each with its real price and a ready-to-call pay_url.
Otto only recommends. You pay each service directly at its pay_url. There is no prepay wallet, no held balance, and zero markup on the downstream services.
Base URL: https://x402.ottoai.services
The Router is canonical at x402.ottoai.services/meta-intelligence — the same host as every other Otto x402 service. (Under the hood it is served by Otto’s open-router service, fronted by the x402 router as a transparent pass-through.)
Pricing: $0.001 per call (USDC on Base) — a flat router fee, never a markup on the services it recommends.
Custody: Meta Intelligence is non-custodial — it only recommends; you pay each service directly. Otto never holds your funds.
How it works
Every query returns two clearly-labeled candidate pools — never blended into one anonymous ranked list:
| Pool | Source | Verification |
|---|
otto_verified | Otto’s own published x402 endpoints (owned, evidence-backed) | verified |
open_bazaar_candidates | Live CDP Bazaar search (free public marketplace, per-ask) | unverified |
source and verification labels so you always know where a recommendation came from.
quality_score now reflects live-status + on-chain (x402scan) volume where measured — candidates are ranked by liveness and real on-chain usage, never fabricated ratings. It stays null for a candidate until it has been probed/measured, and uptime_pct is only populated where directly observed. Otto never fabricates quality signals.
Endpoints
POST /meta-intelligence — Meta Intelligence
The core product. Returns top Otto-verified endpoints plus live CDP Bazaar candidates for your ask.
POST /meta remains as a back-compat alias of /meta-intelligence.

GET /stats — Registry counts
Returns the verified + Bazaar registry counts and the current fence state.

"registry": { "verified": 51, "bazaar": 33 },
"x402Enabled": true,
"fullAutoEnabled": false,
"refundsEnabled": true
}
POST /feedback — Feedback & Refunds (live)
Rate a paid call and claim a refund. An approved refund returns only to the original payer and never more than you actually paid Otto, with a $10/day budget cap and a required ≥50-word entitlement reason (abuse-resistant by design). Live and paid.
Coming next (not yet live)
One further Router pillar is built behind a fence and is not live — it ships once finalized and Founder-armed. Do not depend on it yet:
POST /full-auto — Full Auto. The Router picks the best service and pays it on your behalf, at-cost, then returns the data. No prepay, no standing balance — per-call pass-through, zero markup. Returns 503 until armed.
Discovery
Honesty constraints
| Constraint | Guarantee |
|---|
| No held balance | Meta Intelligence never takes custody — you pay each service directly |
| Zero markup | The Router fee is flat $0.001; downstream services are passed through at their real price |
| Measured quality only | quality_score reflects liveness + on-chain (x402scan) volume where measured; null until a candidate is probed — never fabricated |
| Blunt source labels | Every candidate is tagged ours / cdp-bazaar and verified / unverified |
