How to pay
Call an endpoint, read the price in the 402 answer, and pay from your own wallet with any x402 client on Base. The payment goes straight to the provider: Autonomo lists this API but isn't part of the payment. See The x402 directory.
Paid endpoints
5 endpoints, sorted by usage. Prices are per request.
| Endpoint | Price | Network | Facilitator | Calls / 30d |
|---|---|---|---|---|
POST/v1/bazaar-listing-check Derives payTo from the live 402 challenge if not supplied, first tries the CDP natural-language search filtered by payTo, then paginates the CDP merchant discovery list for that payTo (100 entries per page, the CDP maximum; parallel, up to 400 pages, failed pages are retried within the time budget) and looks for the exact resource URL. "not_listed" is only returned after a complete scan with a stable total; otherwise the verdict is "unknown". | $0.003 | Base | Coinbase CDP | 1 |
POST/v1/hybrid-search Ranks up to 100 supplied documents twice: lexically with BM25 (same implementation and defaults as bm25-search) and semantically by cosine similarity of embeddings computed locally (multilingual: intfloat/multilingual-e5-small, MIT, with the required "query: "/"passage: " prefixes, truncation at 512 tokens; english: sentence-transformers/all-MiniLM-L6-v2, Apache-2.0, truncation at 256 word pieces; mean pooling and L2 normalization, int8 ONNX exports from the model repositories, pinned and… | $0.005 | Base | Coinbase CDP | 1 |
POST/v1/rag-metrics All metrics are defined in the response. With relevant_ids: precision@k and recall@k over the first k contexts, MRR, average precision and nDCG@k with binary relevance and log2 discount. Without relevant_ids, a context counts as relevant when it supports the reference (or the question if no reference) at or above the threshold; context precision = mean of precision@i over relevant positions (rank-weighted, as in RAGAS but without an LLM judge). | $0.004 | Base | Coinbase CDP | 1 |
POST/v1/rerank Scores every (query, passage) pair with a cross-encoder run locally through transformers.js/ONNX Runtime and sorts by the model logit; relevance is the logistic sigmoid of the logit. multilingual: cross-encoder/mmarco-mMiniLMv2-L12-H384-v1 (Apache-2.0, trained on mMARCO: en, ar, zh, nl, fr, de, hi, id, it, ja, pt, ru, es, vi). english: cross-encoder/ms-marco-MiniLM-L6-v2 (Apache-2.0, MS MARCO, English only). | $0.005 | Base | Coinbase CDP | 1 |
POST/v1/x402-spend-report Queries Transfer events from the wallet on Base mainnet via public RPC in 10,000-block windows and sums them by recipient and by UTC day. Timestamps are derived from block numbers using the fixed 2-second Base block time, anchored at the latest block (or at to_block for a fixed historical window). Covers token transfers only (no ETH gas). Useful for checking what an autonomous agent actually paid for x402 calls. | $0.003 | Base | Coinbase CDP | 1 |
