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+, 51.8/100), which weighs availability, payability and on-chain demand. How the two differ
| Valid payment requirements | 10/10 | Payment requirements carry a payee, a mainnet network and a price. |
| Live 402 challenge | 25/25 | Paid endpoint answers with an HTTP 402 challenge (1427 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 | 22/22 probes succeeded over 30 days (100%). |
| Resource declaration | 10/10 | Declares 9 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 | 3/5 | seen within 30 days; declares x402. |
| Security declaration | n/a | Payment is the access control for an x402 resource. |

Before an ALGO/USDC swap on Algorand: what a full round trip actually costs at your size. Measured slippage, fees and price impact at $100 / $1000 / $5000 from live DEX pools - the measured end-to-end effect, not the declared fee. Refreshed 3x/day. Use it to size a trade or check a quote.
https://api.depth402.workers.dev/dati/soglia-viva
Is the ALGO/USDC gap between Algorand's two main pools worth attention right now? Returns the two-leg arbitrage break-even threshold in basis points, recomputed from real on-chain reserves at every reading, and the observed gap. Gap below threshold = no opportunity. Screening, not an execution trigg
https://api.depth402.workers.dev/dati/pool-onchain
Check an aggregator's ALGO/USDC liquidity against the chain. Returns the reserves of Algorand's two main AMM pools read directly from the pool accounts, the implied price per pool, and the measured gap between aggregator-declared and recomputed liquidity - the check, not someone else's number.
https://api.depth402.workers.dev/dati/mercato-algo
Cross-check an ALGO/USDC price before you act on it. Returns the price implied by the on-chain AMM reserves of Algorand's two main pools, the measured divergence across three independent external sources (the measurement, never their numbers), and the current network fee. Refreshed 3x/day.
https://api.depth402.workers.dev/dati/costo-giro-storico
Reconstruct what an ALGO/USDC swap cost on a past date, or audit a past execution. Full historical series of the measured round-trip cost (slippage and fees) by trade size on Algorand DEX pools, one entry per probe run since 26 July 2026, in one call. Yesterday's quotes cannot be asked again.
https://api.depth402.workers.dev/dati/divario-storico
Answer, for a past window, whether an ALGO/USDC two-leg arbitrage on Algorand was ever worth doing. Full series of the break-even threshold against the observed pool gap, reading by reading since 26 July 2026, in one call. The reserves of the past cannot be re-read from the chain.
https://api.depth402.workers.dev/dati/stabilita-costo-giro
Decide whether one ALGO/USDC cost reading is enough to act on. Minimum, maximum, mean and latest measured round-trip cost by trade size across the whole series recorded on Algorand DEX pools since 26 July 2026 - the spread tells you if a single quote is dependable or moves too much to trust.

The measured historical series - round-trip cost, arbitrage break-even, or cost-stability - Ed25519-signed over canonical JSON as a portable, independently verifiable artifact. One entry per probe run since 26 July 2026. Reserve history cannot be rebuilt from free endpoints after the fact: this exis

Signed pre-trade attestation of ALGO/USDC swap cost, measured from live AMM reserves at an exact Algorand round. For your size (or a standard grid): reserve-implied output, effective price and price impact on the two main pools, Ed25519-signed over canonical JSON with round, reserves and method URL
