Migration Kit — switch x402 endpoints in one line

Already paying some other x402 API? Every endpoint in this fleet speaks the same x402 v2 protocol (exact scheme, USDC on Base, same facilitator pattern). Switching is three small changes: the URL, 0–2 input field names, and your spend cap. Your wallet, signer and payment code do not change — and your first calls here are free trial calls, so you can verify the output shape before you pay anything.

Price-verified switch map

Reference prices are the named seller's Bazaar price or the category median (sources in the last column — snapshots, not live quotes). Our prices were live-checked on 2026-10-25 against the fleet manifest and the live code generator; the generator below always reads current prices. Machine-readable version: migration-map.json.

Any other endpoint in the fleet (58 payable endpoints) switches the same way — pick it in the generator below. Full manifest: /.well-known/x402.

1-click switch generator

Generates ready-to-run code for the endpoint you pick, from the fleet's live code generator (codegen) — the price and URL in the code are read live, never hard-coded here.


Try it live — free trial, right here

No signup, no payment: these buttons make a real free-trial call from your browser to the live fleet (daily trial quota per visitor). This is the exact response shape your agent gets before it ever pays.


Migration checklist (≈2 minutes)

  1. Keep everything payment-related. Same wallet, same signer, same facilitator flow — this fleet is x402 v2, exact scheme, USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base (eip155:8453), payTo 0x198f3895551B309fF5C5F59e690FB0823d10EA93.
  2. Swap the URL to the endpoint in the table.
  3. Rename input fields per the table (most are identical; the one that bites is aiverdict's contract).
  4. Run the free trial first. First calls per day are served free — compare the output shape with your current provider before any payment path is exercised. If a call fails to settle later, the free 402 Clinic diagnoses the payload.
  5. Lower your spend cap to the new price (the generator's guard does this) — your old cap stays valid, it just over-authorizes.
Honesty note: competitor figures are snapshots recorded on the dates shown (CDP Bazaar demand pull 2026-10-19; Tanod category snapshot 2026-10-09), not live quotes — a specific seller may charge more or less today. What is live is our side: prices in the generated code come from the running fleet at generation time. Switching costs nothing to test: trial calls are free.
