What named entity extraction APIs cost over x402

Snapshot 2026-10-10

An agent can send text to an endpoint that returns the people, organizations and places in it and pay for the call over x402. We index the x402 Bazaar daily, so here is what those listings charge on 2026-10-10. The short version: we found only 8 distinct priced named entity extraction offers for free text, on 8 hosts, so the figures below rest on a small sample. The median is USD 0.007 per call, the lowest is USD 0.001 and the highest USD 0.25. Tanod charges USD 0.001 per call, which is the lowest price listed and below the median: 0 listings are lower, 1 lists the same and 7 are higher. The comparison is not like for like: Tanod runs a small English spaCy model, while the other listings range from a rule-based tagger to a large language model, and two say they work in any language. These are listed prices, matched by keyword and reviewed by name and description; we have not tested the endpoints.

Median listed x402 price for named entity extraction: USD 0.007 per call across 8 offers on 8 hosts (snapshot 2026-10-10). Tanod: USD 0.001 (at the lowest listed price, below the median).

The numbers

Price histogram

Prices are per call as listed, in USD, not a measure of accuracy, recall or uptime. With 8 offers a single listing moves the percentiles a lot. Where listings name a method, one is rule-based (patterns and word lists), one uses Claude Haiku, and the rest do not say.

8 offers

All offers found, ordered by price. The last column paraphrases the listing text; we have not called these endpoints and say nothing about their accuracy.

Method

• Source: Tanod's agent index of the x402 Bazaar and PayAI, queried 2026-10-10 (newest listing seen 2026-10-09T04:31:37Z), listings last seen on or after 2026-10-07. Internal-only sources, Circle-sourced rows and Tanod's own routes are not used.
• Match: listings with a price above zero whose URL, name or description combines named entity, NER, entity extraction or entity recognition wording, or lists people with organizations and places or locations. About 110 distinct URLs matched and were reviewed by name and description. Only endpoints whose main job is to return people, organizations or places from text the caller sends were kept: 8 offers on 8 hosts.
• Excluded: extractors of emails, URLs, phone numbers, addresses and amounts by pattern, PII detection and redaction, keyword and keyphrase endpoints that also mention entities (two listings), page-based extractors that take a URL rather than text (for example intel.rallylive.ca/page/entities), summarizers and web page briefs that include entities among other fields, company, legal-entity (LEI) and Wikidata lookups, sanctions screening of names, blockchain address labels, knowledge-graph search, and two routes on one host named text/entities with no description, which we could not classify. A looser rule would find more, and a stricter one fewer.
• Deduplicated by URL. Hosts are counted by host name. Listed price is the first payment requirement; some endpoints may charge differently by input length. Percentiles are linear interpolation between ranks. Median of 8 prices is the average of the 4th and 5th values (0.007).

Where Tanod fits

POST /v1/ner takes an English text of up to 20,000 characters and an optional labels list to keep only some types. It runs spaCy en_core_web_sm 3.8.0 (MIT) and returns each entity with its text, label and character offsets (Unicode code points, end exclusive), plus a count per label. The labels are the 18 OntoNotes types: PERSON, ORG, GPE, LOC, FAC, NORP, DATE, TIME, MONEY, PERCENT, QUANTITY, CARDINAL, ORDINAL, EVENT, LAW, LANGUAGE, PRODUCT and WORK_OF_ART. Long text is processed in chunks, and at most 2,000 entities are returned, after which the response says it was truncated. It is a small statistical model: it can miss or mislabel entities, and it does not link them to a database or merge repeated mentions. It typically answers in under 0.1 s for 2,000 characters, runs on Tanod's own server without a language-model provider, and costs USD 0.001 per call, paid in USDC on Base or Polygon with x402. 5 free mlpeek calls per IP per UTC day are shared with the other mlpeek routes. The MCP tool is extract_entities at https://tanod.dev/mcp. Details are in the named entity recognition guide.

When a priced listing above is the better choice

• Your text is not English: the Tanod model is English only, and two listings say they handle any language.
• You need an LLM's reading of context, for example business terms, or only entities that the text states explicitly with an evidence snippet; the pricier listings describe that.
• You need entities from a very long document in one call: Tanod stops at 20,000 characters per call.
• You need keywords with the entities in one response; two listings return both.

When Tanod fits

• You want the lowest listed price, USD 0.001 per call, with a free allowance for trying it.
• You want character offsets for every entity, a count per type and a label filter, from a documented named model and version.
• You want a deterministic result for English text with no model provider in the path.
